The family comprises Acrobat Reader (formerly Reader), Acrobat Pro, and Acrobat.com. The basic Acrobat Reader, available for several desktop and mobile platforms, is freeware; it supports viewing, printing, scaling or resizing and annotating of PDF files. Additional, "Premium", services are available on paid subscription. The commercialproprietary Acrobat, available for Microsoft Windows, macOS, and mobile, can also create, edit, convert, digitally sign, encrypt, export and publish PDF files. Acrobat.com complements the family with a variety of enterprise content management and file hosting services.
Purpose
The main function of Adobe Acrobat is creating, viewing, and editing PDF documents. It can import popular document and image formats and save them as PDF. It is also possible to import a scanner's output, a website, or the contents of the Windows clipboard.
Because of the nature of the PDF, however, once a PDF document is created, its natural organization and flow cannot be meaningfully modified. In other words, Adobe Acrobat is able to modify the contents of paragraphs and images, but doing so does not repaginate the whole document to accommodate for a longer or shorter document. Acrobat can crop PDF pages, change their order, manipulate hyperlinks, digitally sign a PDF file, add comments, redact certain parts of the PDF file, and ensure its adherence to such standards as PDF/A.
Adobe has renamed the Acrobat products several times, in addition to merging, splitting and discontinuing them. Initially, the offered products were called Acrobat Reader, Acrobat Exchange and Acrobat Distiller. "Acrobat Exchange" soon became "Acrobat". Over time, "Acrobat Reader" became "Reader". Between versions 3 and 5, Acrobat did not have several editions.[clarification needed] In 1999, the Acrobat.com service came to being and introduced several web services whose names started with "Acrobat", but eventually, "Acrobat.com" was downgraded from the name of the family of services, to that of one of those services.
Unlike most other Adobe products, such as members of Adobe Creative Suite family, the Acrobat products do not have icons that display two letters on a colored rectangle.
Document Cloud
In April 2015, Adobe introduced the "Document Cloud" branding to signify its adoption of the cloud storage and the software as a service model for enterprise companies. This release included a new version of Acrobat called "Acrobat DC." Following the introduction of Document Cloud, Acrobat.com, which served a similar function, was discontinued.
The GUI had major changes with the introduction of Acrobat DC in 2015, which supports Windows 7 and later, and OS X 10.9 and later. Version numbers are now identified by the last two digits of the year of major release, and the month and year is specified; the previous version was 12, but examples of the DC (Document Cloud) Acrobat product family versions are DC June 2016, version 15.016.20045, released 2 June 2016 and DC Classic January 2016, version 15.006.30119, released 12 January 2016. From DC 2015 the Acrobat family is available in two tracks, the original track, now named Classic, and the Continuous track. Updates for the Classic track are released quarterly, and do not include new features, whereas updates for the Continuous track are issued more frequently, and implemented silently and automatically.
The last pre-DC version, Acrobat XI, was updated to 11.0.23 version (and this was the final release) on November 14, 2017, support for which had ended a month earlier on October 15, 2017. In September 2020, Adobe released a feature to make documents easier to read on phones called "Liquid Mode" using its Sensei AI.

Supported file formats
The table below contains some of the supported file formats that can be opened or accessed in Adobe Acrobat.
Adobe Acrobat is available in the following languages: Arabic, Chinese Simplified, Chinese Traditional, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Turkish and Ukrainian. Arabic and Hebrew versions are available from WinSoft International, Adobe Systems' internationalization and localization partner.
Before Adobe Acrobat DC, separate Arabic and Hebrew versions were developed specifically for these languages, which are normally written right-to-left. These versions include special TouchUp properties to manage digits, ligatures option and paragraph direction in right-to-left Middle Eastern scripts such as Arabic, Hebrew, and Persian, as well as standard left-to-right Indian scripts such as Devanagari and Gujarati. The Web Capture feature can convert single web pages or entire web sites into PDF files, while preserving the content's original text encoding. Acrobat can also copy Arabic and Hebrew text to the system clipboard in its original encoding; if the target application is also compatible with the text encoding, then the text will appear in the correct script.
Security
A comprehensive list of security bulletins for most Adobe products and related versions is published on their Security bulletins and advisories page and in other related venues. In particular, the detailed history of security updates for all versions of Adobe Acrobat has been made public.
From Version 3.02 onwards, Acrobat Reader has included support for JavaScript. This functionality allows a PDF document creator to include code which executes when the document is read. Malicious PDF files that attempt to attack security vulnerabilities can be attached to links on web pages or distributed as email attachments. While JavaScript is designed without direct access to the file system to make it "safe", vulnerabilities have been reported for abuses such as distributing malicious code by Acrobat programs. Adobe applications had become the most popular client-software targets for attackers during the last quarter of 2009.
On September 13, 2006, David Kierznowski provided sample PDF files illustrating JavaScript vulnerabilities. Since at least version 6, JavaScript can be disabled using the preferences menu and embedded URLs that are launched are intercepted by a security warning dialog box to either allow or block the website from activating.
On February 19, 2009, Adobe released a Security Bulletin announcing JavaScript vulnerabilities in Adobe Reader and Acrobat versions 9 and earlier. As a workaround for this issue, US-CERT recommended disabling JavaScript in the affected Adobe products, canceling integration with Windows shell and web browsers (while carrying out an extended version of de-integration for Internet Explorer), deactivating Adobe indexing services and avoiding all PDF files from external sources.
Adobe has identified critical vulnerabilities in Adobe Reader and Acrobat XI (11.0.01 and earlier) for Windows and Macintosh, 9.5.3 and earlier 9.x versions. These vulnerabilities could cause the application to crash and potentially allow an attacker to take control of the affected system. There have been reports of these vulnerabilities being exploited to trick Windows users into clicking on a malicious PDF file delivered in an email message. Adobe recommended users update their product installations.
Adobe has released security updates for Adobe Acrobat and Reader for Windows and Macintosh. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.
In April 2026, Adobe Inc. released an emergency patch for a zero-day vulnerability in Acrobat and Acrobat Reader, tracked as CVE-2026-34621, which had been actively exploited prior to disclosure. The vulnerability, a prototype pollution flaw enabling arbitrary code execution, was discovered by independent researcher Haifei Li and addressed in version 26.001.21411.
